    I wholehardedly agree, however, those that thought that 5.45 was a good fit for the AR platform and invested in such found that the "it'll work in a 5.56 magazine" claims of several manufacturers just weren't quite true. Since no one of note really makes a reliable 5.45 magazine for the AR platform that leaves those so invested searching for a workable alternative. Me, when and if I buy a 5.45 rifle it'll be an SGL-31.

    I've burnt the barrel out of my 5.45 AR through heavy usage and just had it replaced so I feel that I'm qualified to comment.

    C Products makes the only dedicated 5.45 AR mags. They have just been acquired and their website is gone. So.....AR owners who invariably own a 5.56 AR as well wonder what mags will work with the 5.45 cartridge. Answer is E-mags downloaded, older green follower Lancer mags, and newer PMags. Also, in case you don't own both calibers, 5.45 and 5.56 are a **** of a lot closer in size than 9mm and .40.

    Understand why the question was asked? Have any experience with 5.45 ARs?

    Kmrtsn, read my DeFoor class review to see how "unreliable" the C Products mags are. To sum it up, they did better than Lancers in a KAC gun

    Back to the main topic...

    I got two of these Troy CBIR mags in the mail today from AIM. Haven't had a chance to use them live just yet, but here are some initial impressions:
    -overall size, shape, and feel very similar to a Pmag
    -plastic feels thinner and more flexible than a Pmag, whether current Rev M or early (5/07) type Pmags
    -the feedlip area (top 3/8" of mag) is a different sheen of plastic and feels stiffer than the rest of the mag - possibly either a different type of plastic or an internal insert molded inside (Troy claims reinforced feedlips)
    -using the completely unscientific pencil eraser test, the mag follower seems only fair at anti-tilt, and not anywhere near as good as Pmags or TangoDown ARC mags
    -I like the fish scale texture on the mags - BUT the main flats of the mags are smooth, no texture or ridges, which is likely to be an issue for the way I normally remove mags from pouches. The texture is in the areas that are useful if you use a "beer can grip" to remove mags from pouches.
    -The mags fit easily and dropped free with no resistance when tried in lowers made by Armalite, Bushmaster, Aero Precision, and Charles Daly.
    -Troy claims these have a special feature to prevent any over-insertion, but looking at the mag I can't identify it. There is nothing resembling the ridge on an ARC mag, for example.
    -The floorplate catch system appears similar to that on an original Lancer L5 magazine
    -The little gripper/bumper piece on the one floorplate is a rubbery material and appears useful, although it may require a different grip than either magpuls (the floorplate device) or other types of polymer mags.

    The proof is in the testing and I don't know if I'll get to try them this weekend. My initial impressions are, sadly, of a Pmag knockoff that doesn't offer anything better. I hope to be proven wrong.

    You're absolutely right, carry on, forget I was here.

    A co-worker tried to sell me his a couple of years ago. At first I was excited about the prospect of really cheap ammo in the platform but came away from trying it out unimpressed. My exposure may not have been ideal, he had only one metal 5.45 magazine (unknown brand) and was trying to make 5.56 mags work. None of them seemed to run right and my internet shopping at the time for purpose built 5.45 mags came up with nothing so I let the offer pass.

    How many did you buy? Was it the three for $42 deal? Based on your initial impressions the cost of these would have to drop considerably to sway from P-Mags.

    I put about 180 rounds through a couple of these mags today. My thoughts below.

    1. They functioned and dropped free with no issues in either an AR or a SCAR (tested both).
    2. 30 rounds loaded up, no problem.
    3. I was able to insert them on a closed bolt without major issue on both platforms. Additional force was required but it was successful.
    4. I did a fair amount of drop testing on concrete (4 feet). This quickly escalated to drop testing from 6 ft to throwing them up, hitting the ceiling (8 feet) and dropping on concrete. I also chucked them against cinder block walls several times, threw them down range when I went to check on my target, and stepped on them. The front corners of the feed lips smeared or deformed slightly but there was no hiccup in the function. I'll continue to run one of the mags in any future shooting. I also tossed a PMag in a similar manner, saw similar deformation, and saw no change in function.
    5. The floorplate protector does seem to mitigate some of the force of an impact on concrete. It has kind of a weird "squishy" feeling if you use the magazine for a monopod but it was solid enough for hasty accuracy.
    6. The Troy mags will fit in a Kydex mag holder sized for a PMag but are definitely looser. I don't know if they would stay in under a lot of running and movement.

    If I think of any more observations, I'll edit this post.

    I wasn't really about to draw any hard and fast conclusions other than I would continue to use this one on a trial basis prior to purchase any more.

    one advantage I see over the pmags is the flush floorplate vs the magpuls fatter floorplate. Should make the troys easier to put in rigs and pouches when doublestacked
